You do not want to connect the blue and black wires together at the same location when installing Hopkins Agility Electric Brake Controller, # HM47294. I have included the wire color/functions of the brake controller below.
White = Ground (negative battery terminal)
Blue = output to trailer brakes
Red = stop light wire on brake switch
Black = 12 volt power (positive battery terminal via a 20/30 amp circuit breaker per instructions)
If you were to connect the blue wire to the 12 volt power source, the trailer brakes would be on all the time. If you can tell me the year, make, and model of the vehicle, I can provide more specific installation instructions.
